What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: To explore serum inflammatory factors and 25-hydroxyvitamin D and diabetic vascular lesions in patients with T2DM. Methods: A total of 362 adult (aged 18 years) patients with T2DM hospitalised from April 2022 to June 2024 were selected as research subjects. A patient's body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), age, sex, and length of illness were among the general data gathered. Blood parameters, glycated haemoglobin (HbA1c), fasting blood glucose (FPG), total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), inflammatory factors [C-reactive protein (CRP), interleukin-6 (IL-6)], and 25-hydroxyvitamin D [25(OH) D] were determined. The homeostatic model assessment of insulin resistance index (HOMA-IR) and the systemic inflammatory index (SII) were computed. The vascular lesions were divided into three groups: the simple T2DM group (155 patients), the T2DM microvascular lesion group (122 patients), and the T2DM macrovascular lesion group (85 patients). One-way analysis of variance, the Kruskal-Wallis H test, or the c2 test was used for comparisons among multiple groups. The relationship between 25(OH) D and several inflammatory markers was examined using Spearman correlation analysis, and the factors influencing diabetic vascular lesions were analysed using multivariate logistic regression analysis. Results: The levels of 25(OH) D in both the T2DM microvascular lesion group and the T2DM macrovascular lesion group were significantly lower than those in the simple T2DM group (P<0.05). The level of IL-6 in the T2DM microvascular lesion group was significantly greater than that in the simple T2DM group (P<0.05). Compared to the simple T2DM group and the T2DM microvascular lesion group, the T2DM macrovascular lesion group had significantly higher levels of CRP IL-6, and the SII (P< 0.05). Multivariate logistic regression analysis results showed that after controlling for confounding variables. With the simple T2DM group as the reference, CRP (OR= 5.35, 95% CI 1.49-19.13) and 25(OH) D (OR= 0.88, 95% CI 0.78-0.98) were the influencing factors of microvascular lesions in T2DM patients; CRP IL-6, SII, and 25(OH) D were influencing factors of macrovascular lesions in type 2 diabetes mellitus (T2DM) patients (OR = 14.99, 95% CI 2.84-79.13; OR= 27.92, 95% CI 4.24-183.92; OR= 1.01, 95% CI 1.00-1.02; OR= 0.74, 95% CI 0.60-0.92). Spearman correlation analysis revealed a negative correlation between CRP and IL-6 (r= 0.600, P<0.001) and between CRP and the SII (r= 0.256, P<0.001), while IL-6 showed a positive correlation with the SII (r= 0.307, P< 0.001). Additionally, 25(OH) D had a negative correlation with CRP (r=-0.102, P= 0.052), IL-6 (r=-0.115, P= 0.028), and the SII (r=-0.141, P=0.007). Conclusions: Compared with those in patients with T2DM microvascular lesions, the levels of the inflammatory factors CRP and IL-6 and the SII in the serum of patients with T2DM macrovascular lesions are greater, and the level of 25(OH) D is lower.
